Over which interval is the graph of f(x)= -x^2 +3x+ 8 increasingly
Accepted Solution
A:
Answer:x<1.5Step-by-step explanation:The equation is [tex]f(x)=-x^2+3x+8[/tex]Use a graphing tool to find the vertex of the parabola.When you get the vertex from the graph, you can now write the increase as ; all x-values less than the x-value of the vertex value in the graphFrom the graph, the vertex is at (1.5,10.25), the parabola opens down with maximum value y=10.25The interval of increase is x<1.5
